1. Calculate the heat required to raise the temperature of 1.5 mol of benzene from 300oC
to 700oC in a steady-flow process at a pressure sufficiently low that may be considered as
an ideal gas. Tip: Please read the textbook page 125-127 and pay particular

1. A steam turbine operates adiabatically with a stream rate of 25 kg/s. Steam is supplied at
1300 kPa and 400 C and discharges at 40 kPa and 100 C. Determine the power output of the
turbine and the efficiency of its operation in comparison to a turbine t

You should use the data at 0oC and 100oC to build the calibration curve for the temperature scale. The
obtained correlation is V (cm3/g)= 0.000013421*T(oC)+0.073556
Using the correlation equation, we obtained
